What does "bottled at cask strength" mean?

The phrase "bottled at cask strength" refers to the practice of bottling whiskey at the same proof it is at when it is removed from the barrel, without any dilution. This encapsulates the full flavor and intensity of the spirit as it has developed during its aging process. Cask strength bourbons are known for their higher alcohol content since they are not adjusted with water, allowing enthusiasts to experience the whiskey in its most authentic form.

This method highlights the natural characteristics of the bourbon, unaltered by additional processing or dilution, and is often sought after by bourbon aficionados who appreciate the richer flavors and complexities that come with this approach.
